Shock! Artist stops to look around Scunthorpe on vacation (10)
I believe the answer is:
scandalise
'shock' is the definition.
(scandalise can mean to shock or appal)
'artist stops to look around scunthorpe on vacation' is the wordplay.
'artist' becomes 'Dali' (Salvador Dali).
'stops' means one lot of letters goes inside another.
'to look around' becomes 'scan' (as in scanning a room).
'on vacation' says to hollow out the word (remove centre letters).
'scunthorpe' with its middle removed is 'se'.
'scan'+'se'='scanse'
'dali' inserted into 'scanse' is 'SCANDALISE'.
(Other definitions for scandalise that I've seen before include "cause sensation" , "Shock by impropriety" .)
